What is tooth sensitivity and why does it affect so many people?

Tooth sensitivity (or dentine hypersensitivity) is a common condition that manifests itself as a brief, sharp, transient pain felt on contact with certain stimuli: cold, hot, sweet, acidic or even simply when brushing. This sensation is due to exposure of the dentin, the inner layer of the tooth, normally protected by the enamel or gum.

When part of the dentin becomes exposed, microscopic channels, called dentinal tubuli, allow external stimuli to reach the dental nerve, causing this characteristic pain.

Tooth sensitivity is not a serious pathology in itself, but it can impair quality of life, interfere with eating or brushing, and be a sign of an underlying problem (erosion, gingival recession, bruxism...).

What are the most common causes of tooth sensitivity?

Several factors can contribute to the onset or aggravation of tooth sensitivity:

Enamel erosion: caused by acidic foods (fruit juices, soft drinks, vinegar, citrus fruits) or gastric reflux.
Aggressive brushing: brushing too vigorously or with a hard-bristled brush can wear away enamel or cause gingival retraction.
Excessive use of whitening products: certain toothpastes or cosmetic treatments can weaken the tooth surface.
Gingival recession: linked to age, periodontal disease or inadequate brushing, it exposes tooth roots unprotected by enamel.
Mineral deficiencies or inadequate hygiene: lack of fluoride, calcium or irregular oral hygiene can weaken enamel.
Recent dental care: certain scaling, bleaching or restorative treatments can trigger temporary sensitivity.

Identifying the cause enables you to choose the right solution, whether preventive, soothing or restorative.

What treatment should be chosen for tooth sensitivity?

The treatment of tooth sensitivity is based on several types of products, acting in complementary ways:

Desensitizing toothpastes

Contain active ingredients such as potassium nitrate, sodium fluoride, strontium chloride or hydroxyapatite complexes.
Act by blocking dentinal tubules or reinforcing enamel mineralization.
Use daily for at least two to three weeks for a gradual effect.

Remineralizing mouthwashes

Help strengthen enamel and reduce gingival inflammation.
Gentle, alcohol-free formulas with fluoride, calcium or soothing plant ingredients.
Complement the action of toothpaste and protect sensitive areas between brushings.

Protective or remineralizing gels

Apply directly to sensitive teeth for targeted action.
Useful in case of localized pain or after dental care (scaling, polishing).

Ultrasoft toothbrushes

Essential to avoid aggravating gum erosion or recession.
Efficient brushing without damaging gums.

Remineralizing supplements

Targeted calcium, magnesium and vitamin D to strengthen dental health from within.
Of interest in cases of acidic terrain or overall bone weakness.

Which plants or natural active ingredients can relieve tooth sensitivity?

Some natural active ingredients are recognized for their soothing, astringent or restorative properties, in support of conventional treatments:

White clay: remineralizing and gentle, used in some natural toothpastes.
Ratanhia (Krameria triandra): astringent plant, tones gums and strengthens dental tissue.
Chamomile and calendula: anti-inflammatory and soothing properties, used in mouthwash or gel.
Propolis: natural antiseptic, promotes mucous membrane regeneration.
Arnica: applied externally to relieve pain after dental treatment.

These active ingredients are often found in organic or certified natural oral care products, for a more respectful approach to oral balance.

What good habits should I adopt to prevent tooth sensitivity?

As well as using the right care products, it's essential to adopt preventive daily habits:

Use a soft brush and non-abrasive toothpaste
Brush your teeth 2 or 3 times a day, using a gentle, appropriate technique.
Avoid brushing immediately after eating acidic foods (wait 30 minutes)
Limit highly acidic or sweet foods
Do not overuse whitening or abrasive products
In the event of bruxism, consult a dental hygienist for a night guard
Consult a dental surgeon regularly for personalized follow-up.

These simple gestures reinforce the natural enamel barrier and prevent dentine exposure.
